Investigate the effect that different weights have on my parachute.

Introduction

Experiment of Parachute

Investigation

          We are going to investigate the effect that different weights have on my parachute. We are going to construct a parachute and drop it from an unchanged height with different weights attached to it and record the results.

        To make my experiment, my parachute will be constructed from a black bin liner which will be 70cm x 80cm and the string will be 30cm long. I will have a piece of string coming from each corner of the parachute, joining together at the bottom to tie the weight onto. To make my experiment safe I am going to make sure that the area I am working in and dropping the parachute from is free from people and other various objects, which may obstruct the path of the parachute – this would make the test an unfair one. I am going to change the mass of weights attached to the parachute; therefore this will be my dependant Variable – the weights will be from 10-grams to 60-grams. Hence, my Independent Variable will be the vertical height that I drop my parachute from. I will also keep the parachute the same – not change the length of the string or the measurements of the bin liner. I am going to measure the time taken for the parachute to reach the ground from the desired height.

Conclusion

If I did the experiment again I would carry it out in a room with a high ceiling – like a hall. This would ensure the parachute had time to unfold, accelerate and gain terminal velocity making the experiment more accurate and precise. I could also maybe use different materials to make the parachute, like tissue paper instead of bin liner and cotton instead of string. If I did this, my results would change and I compare them to the data I have now. The 40g experiment was different to the remainder of my results so I am going to fairly say this is an anomalous result. This could have happened because the parachute’s path was obstructed by maybe a pupil or a stool, which would have slowed down the parachute. Another alternative as to why I gained this anomalous result is that maybe at the time we were carrying out the experiment a gust of wind from an open window may have blew the parachute off course or the classroom door was opened which may have created a draft.

Instead of changing the weight on the parachute I could change the surface area of the bin liner and the length of the string I used, this would vary my results and I could then compare the new data with the data I already have.

    Obviously with a larger canopy you will catch more air whilst falling and so with a larger canopy the time the parachute takes to fall will increase and the spead will decrease. When there is a large amount air resistance the weight is balanced quicker therefore the object reached its
